ttc for baby #2

Me and my so are trying for what will be my second and his first and any time after I've ovulated I get nothing for the cm till I get my af and this time I have a lot and by a lot I mean a lot of creamy cm and will sometimes in the day be sticky and it's confusing me so much I've tried talking with my obgyn and she just shuts me down saying don't worry about it we've been trying for the past two years and I'm 21.. this is really frustrating.
